Disston Company 119917 Hss Black Oxide Drill Bit 5/32 in

Product Description

The DISSTON COMPANY 119917 is a high speed steel jobber-length drill bit finished with a black oxide tempering treatment. It measures 5/32 inches in diameter and 3-1/8 inches in length, with a straight shank and a 135-degree split point. The split point geometry features four cutting edges that eliminate walking on contact, reducing the need for a center punch. The black oxide treatment lowers frictional resistance and improves chip flow during drilling. This bit is suited for use by electricians, plumbers, HVAC technicians, and general tradespeople who need a reliable, everyday drilling tool across a range of common materials.

The 119917 is recommended for wood, plastic, wallboard, plywood, soft metals, aluminum, brass, and bronze. It is also rated for occasional use in stainless steel and other hard metals. Its jobber-length profile makes it a practical choice for standard-depth holes in light framing, enclosures, sheet metal brackets, and panel work — the kind of repetitive drilling tasks found across residential and light commercial jobsites.

Installation Notes

This bit is installed and operated by any trade professional using a corded or cordless drill with a compatible chuck. Secure the straight shank fully in the chuck before operation and confirm the chuck is tightened. When drilling hard metals or stainless steel, use appropriate cutting fluid and reduce feed pressure to extend bit life. Always wear eye protection when drilling.
